By 1998, Sony Computer Entertainment had dethroned video game giants SEGA and Nintendo, both of which had complete dominance in the global game market. And it was all thanks to the use of third-party game developers, something that SEGA and Nintendo lacked since they preferred keeping their developers in-house. And to keep the momentum going, they released a new console in the early 2000s, which became the best-selling video game console of all time, the PlayStation 2.
